I own a 2022 Mercedes-Benz E350. The front glass roof panel located directly above the windshield developed a large crack while the vehicle was parked. The crack extends nearly the full length of the panel and includes areas where the glass has separated along the fracture. I am not aware of any collision, road debris, or object striking the vehicle before the damage was discovered. The damaged panel is available for inspection. I am concerned that if this type of failure were to occur while the vehicle is in motion, broken glass could fall into the passenger compartment or be shed onto the roadway, creating a potential safety hazard for the driver, passengers, and other motorists. The…

This vehicle on an ongoing basis is reporting false speed limits. It consistently abruptly drops the indicated speed limit from 70MPH on [XXX] northbound in Salt Lake City. the vehicle slows itself abruptly in traffic that is sometimes dense and traveling 70 to 80. An eventual rear end collision seems likely which could involve multiple vehicles. It intermittently presents the same risk in other locations with no as yet recognized associated variables such as the one location on [XXX]. Exact start and stop of the erroneous speed limit are not consistent. Sometimes brief and sometimes for a mile or more.

Major issue found with engine cylinder head in various models with 2.0 Liter Turbo charged engines (Engine code M260 or M264). Cylinder heads have premature wear at valve seats, causing engine misfires and unsafe driving conditions. (Sudden loss of power, even on freeways.) Mercedes-Benz had improved cylinder head design to mitigate this issue, thus proving that they knew it was their product quality that is causing these unsafe issues. Mercedes-Benz even put out a service bulletin to address these defective cylinder heads. This publication can be found under XENTRY, Topic Number LI01.30-P-072328, Version 8, published 9/26/2023. My contact at Mercedes Dealer informed me that they are seeing…

On June 16, 2024, while driving my 2022 Mercedes E 350 with my two young children in the car, my sunroof suddenly and literally exploded. Fortunately, the sunroof screen was closed, which prevented us from sustaining any direct injuries. However, the entire sunroof shattered and is now gone. The explosion sounded like a gunshot, causing immediate and extreme distress. My body began shaking uncontrollably from the shock and fear of the incident. This unexpected event posed a severe safety hazard, and I am deeply concerned about the potential risks to other drivers with similar vehicles. **Vehicle Information:** - Make: Mercedes-Benz - Model: E 350 - Year: 2022 - Mileage: 87,000 miles…

My vehicle suddenly stopped in the middle of road. It showed gas tank empty though tank had half tank gas. i would have been hit by a vehicle behind me. Fortunately, there were no vehicles behind me. i filled the remaining half tank , then car started again. I believe that gas sensor was not working. I dropped the vehicle for service to the mercedes benz dealerwith full tank of gas. It was showing empty gas tank and i can drive zero miles. Dealer told me after 3 days that gas tank needs to be replaced. My concern is that , manufacturer might have made a defective gas sensor or gas tank. This may lead for deaths. It may need a recall , if you have received similar complaints. I contacted the…

The panoramic sunroof exploded while inside the car without warning. Contacted the dealership/service center on Friday 9/15/2023, was told they have not received a memo regarding the panoramic sunroofs in the 2022 E350, however; this is a know problem. I was told that this is not covered of my warranty because they assume something had to hit the glass, provided evidence via my security camera that not fell and hit the glass. Even after this happened the warning system did not even go off to indicate there was a problem.
